Hi Rob,
I've loved these tents for years, had a little company that brought these in these tents in to North America called LoftyShelters. Had a really great time doing it but I'm going to be off again on an extended voyage pretty soon. I was going to stop but I found Mike and he wanted to continue with it and AutoHome wanted things more formal so it all fell together so AutoHomeUSA was formed a few years back. I help Mike any way I can. AutoHome is really lucky, a lot of folks help.
Here is my favorite folding contraption and trailer.
And what she looks like deployed
We will have some old clunker with a Columbus on it as our support vehicle for crossing the country and when we are here in the US. When we are on the boat we have folding bicycles to explore on land. I also have a folding kayak in the engine room for those waterways that are too small for the mothership. Kind of a compact folding lifestyle for exploring the world.
I've always kept relationships with many car manufacturers, have done shows for Ford, and with Volvo. I have a soft spot for Jeep, don't we all?, and won Chrysler's Design Excellence award a few years back for a showtruck we put together. I was introducing the concept of rooftop tents back then. Jeep was one of the first manufacturers that really got it. Land Rover has also been supportive, we never would have made the new carbon fiber tents, they underwrote the concept. AM General, not the new Hummer, but the South Bend guys have been especially helpful. They use our equipment sometimes when they are testing their trucks and their engineers would call with suggestions and ideas. They have done extensive testing of all our components for us, they have resources we only dream about. AutoHome tents really benefit from all this help.
Getting back on topic, Mike has been working on coming up with a good side tent for years. It is a really difficult engineering challenge. If you build something like AutoHome's Verandah, it sucks because it has everything we hate about tents, has poles, guy lines, stakes, everything we have come to dislike about tents and why we switched to rooftents. It seems no manufacturer can make a decent side tent because each application is different. You build one that fits a trailer, but then it also has to fit a Land Rover. Then you come up with something that works well, but then it has to stand alone so it can be left back at the campsite. You end up with the Verandah, adjustable in height, stand alone, only trouble, it weighs around 80 pounds, packs in two duffel bags and takes half an hour to set up. Needless to say, you have to twist Mike's arm for him to sell you one. They just aren't a good piece of kit, trying to do too much.
I think the better approach is to specialize and pick the best for your needs and where you are going. Copy what the locals use. That is how I found out about Skin So Soft, I found out about it in Florida because they like it and say it works better than bug repellant. Up in Canada, they must have some crazy system for keeping their dreaded flying insects away. Local knowledge is key, be foolish, ask questions, do what they do no matter how crazy it seems. Then they get a good laugh but you always learn something.
Your question on crossbars is a common one. AutoHome tents only need two, the rest are for the vehicle. Sometimes it is beneficial to use three bars to stress the tent. Some of the guys that go out on class 3+ trails use three bars. The theory is that their vehicles are bending and if you have the tent stressed it will be like a big fiberglass spring and move with the vehicle. Seems to work, but then, from what I've seen a little noise from the tent wouldn't be heard anyway.
